ProtoArc XKM01 review: a full-size foldable keyboard and mouse for travel

Verdict: The ProtoArc XKM01 Gray is a sensible travel kit if you want a full-size 105-key keyboard and numpad with a mouse and device stand included. The tradeoffs are an unlit keyboard, a compact mouse, and separate device switching for the keyboard and mouse.

Pros

• The tri-fold keyboard retains 105 keys and a dedicated number pad.
• The hard case includes a folding stand for a 4–11-inch tablet.
• Two Bluetooth profiles and a 2.4 GHz receiver give the keyboard and mouse three connection channels each. ProtoArc specifications

Cons

• The base XKM01 has no backlight; choose the XKM01 Pro if dim-room typing is important.
• Keyboard and mouse channel controls are separate, so changing devices takes action on both.
• USB-C recharges the devices; it is not a wired data connection. Some Mac shortcuts may also be limited over the receiver. ProtoArc FAQ

Does the fold-out keyboard make travel work easier?

The XKM01 keeps a full-size 105-key layout with numpad, then folds to 8.48 × 4.71 × 0.82 inches. That suits a hotel desk or shared workspace better than a tiny pocket keyboard, while its 12 × 5.6 × 1.6-inch case needs a small bag. The included stand supports phones and tablets, not laptops.

Independent reviews show why the form factor will not suit everyone. Tom’s Guide found the XKM01 quick to set up and liked its tactile, quiet keys during travel use, while noting a preference for a larger mouse shape. The Gadgeteer reviewer found the flat keyboard uncomfortable without a typing angle, needed to press some keys firmly, and disliked the mouse for longer sessions. Both are individual experiences with the XKM01 model, not proof about every user or a confirmation of the current Gray ASIN. Tom’s Guide review The Gadgeteer review

Will keyboard and mouse switch to the same device together?

No. The keyboard and mouse each have their own Bluetooth and receiver controls. If the keyboard is connected to a tablet while the mouse is still connected to a laptop, you must switch the mouse separately. This gives the two devices flexibility, but the kit does not behave like one synchronized multi-device button. ProtoArc FAQ

Both peripherals charge over USB-C, but ProtoArc documents Bluetooth and the 2.4 GHz receiver as their input connections; the charging cable is not a wired operating mode. ProtoArc also cautions that certain function shortcuts may not be supported on macOS when using the USB receiver, and recommends Bluetooth for Mac use. ProtoArc FAQ

The base XKM01 is explicitly unlit. The XKM01 Pro adds three-level white backlighting while retaining a full-size foldable layout. Do not assume the Gray base listing has that feature just because the product family includes a Pro model. ProtoArc XKM01 page ProtoArc XKM01 Pro page

ProtoArc XKM01 Gray specifications

Buy the XKM01 if you will use its full-size foldable keyboard, case and stand away from a desk. Skip it if you need backlighting, a larger mouse, one-step synchronized switching, or a wired keyboard. Check that the listing is Gray model XKM01, ASIN B0BTNMVJ43, from the product page before purchase. ProtoArc specifications Amazon US destination
